Solar panel maintenance: Everything you need to know

Solar panels typically require routine cleaning and maintenance throughout their operational lifespan. Dust, debris, and environmental factors such as weather can gradually impact the performance of photovoltaic cells over time. Ensuring proper upkeep of your solar panels is crucial to maintaining their efficiency and extending their life.

But what exactly does “maintenance” entail for solar panels, and how frequently should you clean them? Does it involve any specialized technical knowledge, or can you handle it yourself? Moreover, are there simple steps you can take to minimize maintenance costs? That’s the focus of this article: providing practical advice on how to maintain your solar panels with minimal stress and expense. Keep reading to discover more.

That’s what this blog is about: how to keep your solar panels functioning optimally with minimal effort and cost. Read on to learn more.

Do solar panels require maintenance?

Yes, solar panels do need some degree of maintenance to ensure they operate at their best and last longer. Occasional rainfall can help remove light dust and debris, but it’s still advisable to have your panels professionally cleaned every 1-2 years, depending on their location and exposure. Additionally, a thorough inspection and servicing every 4-5 years can provide extra reassurance. Our extended warranty, backed by insurance, covers any additional needs, ensuring your solar system remains efficient for years to come.

How often should I clean my solar panels?

Although rain can help keep your panels relatively clean, dirt and debris can accumulate over time, reducing their efficiency. Professional cleaning is generally recommended every 1-2 years, though factors such as proximity to trees, bird activity, and local air quality can influence how often cleaning is necessary. Regularly checking your panels will help you determine when they need attention to maintain peak energy production.

Proper installation and placement of solar panels

Another important consideration is avoiding placing solar panels in areas shaded by trees or near roosting birds. Not only do shadows decrease panel efficiency, but they may also attract birds, which could lead to further issues. This is something any competent solar installation engineer will take into account. During your survey, you can discuss any concerns about the installation with your Solar Together installer.

It’s essential to work with a professional to ensure proper installation. Although solar panels don’t have moving parts, there are several aspects that can go wrong:

• Poorly installed roof anchors can damage your roof tiles or leave the panels insecurely mounted.
• Connecting the panels to an inverter requires careful wiring. Even though the panels are pre-wired, they must still be installed by an MCS-certified installer to avoid issues such as improper grounding or exposed cables.
• If the support legs are installed too low on the panel, it may be positioned at an angle that increases wind load stress.

Poor installation not only increases maintenance needs but can also pose safety risks. High-quality panels and expert (MCS-accredited) installations offered through Solar Together can help mitigate these issues.

Installing bird netting for solar panels

A great way to prevent birds from causing problems for your solar panels is to install netting, “bird barriers,” or bird deterrent kits. These terms refer to similar solutions. When installing your panels, you can opt for mesh, netting, or wire strips that prevent birds from nesting under your solar panels. These barriers also help keep debris like twigs away from your panels. Bird protection is available through Solar Together at a fixed additional cost, and it’s worth discussing with your installer during your on-site survey.

Cleaning solar panels on your roof

We strongly advise against attempting to clean your panels without the proper training and equipment. For those with accessible panels, such as ground-mounted arrays, caution is advised when deciding how to clean them. Some cleaning products can cause damage, and using high-pressure washers can lead to water ingress.

Instead, we recommend consulting a professional cleaning service that can offer industry-standard guidance and services.

Can I hire a solar panel cleaner instead?

While some window cleaners may offer solar panel cleaning services, we suggest using a specialized solar cleaning company. These professionals have the expertise, tools, and training to properly care for your panels while keeping your warranty intact.

How does extreme weather affect solar panels?

Like all electronic devices, solar panels are influenced by extreme weather conditions.

• In freezing temperatures, solar panels function well. Snow covering the panels prevents them from generating electricity, but the panel surface usually allows the snow to melt and slide off.
• In extremely hot conditions, panels produce less voltage and become slightly less efficient.
• In stormy weather, solar panels are resilient. Their waterproof surface keeps them clean and functional. They do not increase the likelihood of your home being struck by lightning.
• In windy conditions, solar panels are secure when installed correctly. They remain stable and safe even in strong winds.

This means that even if you live in an area prone to extreme weather, your panels shouldn’t require additional maintenance. Read our blog to learn more about whether your solar panels work in cloudy conditions.
